Be it known that I, JAMESA MAGNUSEN, a

citizen of the United States of America, and c resident of Chicago,`Cookcounty, Illinois, have invented a certain new and useful Improvement inHinges, of which the follow- My invention relates to improvements inhinges, and has for its object the production of a device whereby aclosed door cannot be removed by withdrawing the pins from the hinges.

A further Objectis the production of a device that willl furnish apositiveflock, and

prevent lateral movement of the leaves ofl the hinge when in closedposition.

A further object 1s the production of a de- 4vice that may be cheaplyconstructed.

These objects are attained by my device,y embodiments of which areillustrated in the accompanying drawings, in whichy Figure 1 representsa plan View of my device. Fig. 2 represents a sectional view lon theline 4 4 of Fig. 1. Fig. 3 represents a plan vieu' of a modification ofmy device. Fig. 4 represents a sectional view on the line o o of Fig. a.I j

Like letters of reference indicate like parts in the several figures ofthe drawings. V

Referring now to the drawings, 8 repre` sents a butt or hingevcomprising leaves 114-12 represent ordinary l apertured knuckles on theleaves; a pin 13 passes through the openings in the knuckles, holdingthe lea-ves in operative relation one with the other. The inner face ofthe leaf 9 is provided with an inwardly projecting ear or lng 16,adapted to fit within an opening 15 in the opposite leaf. This openingis made slightl larger than the projection in order that tie e211 16 mayreadily enter vtherein when the hinge is closed.I This ear is' preferably a portion of the hinge itself punched out and turned at rightangles to the hinge.

In Figs. 3 and 4', the projecting portion 17, on the leaf 9 is formed bypressing a portion ofthe hinge itself inwardly while a cor-` respondingdepression 18 is 4formed in the. 'opposite leaf, the projecting vportion17 ttlng closely within the indentation 18 of the opposite leaf when thehinge is closed.

Whenthe hinge is of the ordinary ty e,

I a `locked door may be lreadily forced from t e inside by withdrawingthe pins from the 'T11 .hinges and prying the door inwardly. The

lock on the door does not serve to hold the door in place against amovement .of this kind, as it is only necessary to swing the doorinwardly a distance of an inch or so on a radius of a circle, with thelock as a center. There is always suiiicient play in locksto permit thisbeing done. The bolt may then be pulled out of the lock and an entranceeffected to the room vor cabinet.k By the use of my improved device,however, the moment the door is closed, the inwardly projecting.. vportion on one leaf of the hinge tits within the opening or depressionin the other leaf,

`preventing lateral displacement of the members when the pin is removed.Of course, this presupposes the fact that the doors lit close y within'the casing. This is almostinvariably the case, soit is fairly safe tosay that my device will, in nearly every case,

prevent the opening ofdoors when the hinge pins are removed.

The construct-ion of my device is extremely simple. Projections may beformed on one leaf and a hole punched through the other, adapted toregister one with the other when the leaves are in closed position. Thejection may be formed integral with the leaf itself by punching outthree sides of the iece and turning an ear inwardly, as shown 1n Fig. 5;or, as shown in Fig. 4, a portion of one o f the leaves'may be pressedinwardly forming a protuberance, adapted to tit within va correspondingindentation formed in the opposite leaf.

` It will thus be seen that the hinge may. be cheaplymanufactured, andat the same time Abe practically irremovable when the door is closed.The device is especially applicable to box cases, cupboards, wardrobes,etc., as well asdoors communicating between apartments.

I claim:

As a new article of manufacture, a hinge comprising a pair of knuckledleaf members, a pin adapte to secure said members .to-

ether, an ear punched from and extending linwardly. from the face of oneof said leaves,

and adapted to enterA within anv opening formed in the opposite leaf.
